[Croup in toxic forms of diphtheria in adults]

Toxic patterns of diphtheria of the fauces in adults are characterized by laryngeal lesions which considerably deteriorate the disease prognosis. The clinical manifestations of diphtheric croup may be unpronounced in such cases and be masked by other severe disease symptoms. If patients with toxic diphtheria develop croup, the necessity of surgical treatment arises at earlier times as compared with cases of isolated croup.
